Style Management about yellowbrick

[bbengfort]

This task requires the ability to modify the visual environment in Yellowbrick similar to how Seaborn does it - but we're happy for ideas about how to do this in more innovative and intuitive ways. For lack of any ideas right now, I'll discuss Seaborn's:

• set_style - set the color scheme and other color properties
• set_context - set the font and size for 'talk', 'poster', 'paper', 'notebook', etc.

See: https://stanford.edu/~mwaskom/software/seaborn/tutorial/aesthetics.html for more.

We also want our own unique visual style that is clean like Seaborn without cloning it. We really like the idea of using Color Brewer as a foundation of our visualizations: https://bl.ocks.org/mbostock/5577023

Question:
Do we want Yellowbrick to blanket overwrite mpl defaults on import? It would then compete with Seaborn as well I think. Who ever gets imported last gets control of the style? (Actually it may make some kind of odd hybrid if we don't perfectly match the various Seaborn changes)

It would be awesome to do an experiment about how the drawing environment
changes by mapping the global parameters (and a potential blog post). I
know I just said this outloud, but for the purposes of documentation:

1. Modify the mpl defaults
2. Visualize using striaght mpl
3. Visualizing using pandas
4. Visualize using seaborn
5. set_context/set_style
6. Visualize using straight mpl
7. Visualize using pandas

And we can watch what is happening/changing.

Made a notebook with some quick experiments. Seems like most things are using the matplotlib rc settings that Seaborn creatively overwrites upon import.

Let me know if I missed anything obvious. Going to start copying over the Seaborn style functionality into Yellowbrick.
